[View this email in your browser]( [logo]( [[WIRED Magazine]1.19.18]( Is President Trump healthy? Well, that depends on your definition of health. Trump is overweight but not obese. He's showing some risk factors for heart disease but he doesn't smoke or drink, and his blood sugar levels are A-OK. His doctor thinks he needs to eat better and exercise more, but he also insists that Trump is in "excellent" health and that he has "great genes." In other words: [It's complicated](. It was only under mounting public pressure that the White House allowed Rear Admiral Ronny Jackson to publicize the details of his examination of Trump, and those results haven't clarified much for those hungry for a better sense of the president's physical and cognitive fitness. For instance, Trump's body mass index puts him just a pound away from obesity—but it's hard to tell how much of a risk that might be without more intensive testing, such as an MRI, to examine how that excess fat might be affecting the president's vital organs. And though Trump passed his physician's cognitive assessment with flying colors, his ability to differentiate a lion from an elephant probably doesn't say much about his appetite for consuming the vast amounts of information necessary to make complex policy decisions. "Whether the president is healthy has consequences on the stability of the nation, but that knowledge has been hard to come by," writes [Adam Rogers](. "Complicating things further, the answers to those impolite but salient questions aren’t, it turns out, straightforward—for anyone, not just a president."

Health How Did President Trump Do on His Physical? It’s Complicated. By Adam Rogers “I wouldn’t call what was described a clean bill of health. There are certainly alerts that need to be followed up. I think his doctor is probably a very good doctor and he did whatever he had to do. And now he knows the guy is overweight, has a high LDL, is over 70, very sedentary, and seems to eat an abominable diet. He knows what he has to do.” critical infrastructure Malware Shows the Dangers of Industrial System Sabotage By Lily Hay Newman If malware can defeat a plant’s safety shutdown features, it can then work to sabotage the system in countless ways. In this attack, though, the malware accidentally triggered emergency system shutdowns that gave it away. As a result, the hackers never revealed the actual payload they had planned to deliver, or the true intent of their attack. Cryptocurrency The Lightning Network Could Make Bitcoin Faster—and Cheaper By Sandra Upson With the Lightning Network in place, they believed, bitcoin could support far more transactions and make them almost-instant, reliable, and cheap, while remaining free of banks and other institutions. In other words, it promised to fulfill the cryptocurrency dream originally set out by Satoshi Nakamoto in 2008. robotics Fear Not the Robot Apocalypse: The Multiplicity Is Here By Matt Simon A great example of multiplicity in action is what Amazon is doing. In its fulfillment centers it employs 100,000 robots that autonomously deliver products to humans, who then pack the boxes that go out to customers. So the tireless robots do the dull task of hurrying around the warehouse, while the humans handle the complex manipulations that would confound a robot.
